A new study published in Transportation Research Record has examined what drivers are likely to do when faced with sun glare-induced blindness. 

The researchers highlighted that temporary visual impairment caused by glare is one of the environmental issues that contributes to traffic accidents.

Around 3000 collisions each year in the US are attributed to sun glare.

The study examined crashes linked to sun glare between 2014 and 2017 in Florida – the ‘Sunshine State.’

They found that running red lights or stop signs was one of the common results of daytime blindness linked to sun glare. Another result of the condition was following the car in front too closely.

Study co-author Mohammadreza Koloushani, shared that there are emerging technologies that could help to reduce the risk when glare is affecting a motorist.

"For example, developing automated avoidance systems that use intelligent transportation technology may prevent crashes when drivers are following other vehicles too closely," he said.

Navigation systems that incorporate real-time information about glare conditions could recommend alternative routes.
